Abstract

We investigate the anomalous chromomagnetic dipole moment (CMDM) μ^tBLHM of the top quark within the bestest little Higgs model (BLHM). Our study incorporates novel interactions arising from the extended Cabibbo-Kobayashi-Maskawa matrix in the BLHM and explores a broad region of the experimentally allowed parameter space, yielding CMDM values on the order of 10−3. This result represents an improvement over previous CMDM calculations within the BLHM and makes it competitive with other beyond the Standard Model scenarios. Experimental and model parameter uncertainties are considered and propagated through our calculations, using a Monte Carlo method.
